Okay so im using my schools iPad. I jail-broke it and found out that they are suspendeding people who jailbreak them. so i deleted cydia and thought all the apps with it would go like ifile and installus but they didn't. So ive been reading alot and i cant figure out how to install cydia back on without restoreing so i thought maybe if i back it up with all the school apps and such then re-install or re jailbreak it , then restore it with the back up data and have cydia plus installus and all the other apps and then be able to delete installus and ifile through cydia. but i have no idea if this will work and im scared ill mess something up. can someone tell me if this will work or if there is another way to fix this ..? please and thank you ):
